Tensei Kenja no Yarinaoshi ~Ore Dake Tsukaeru Kikaku-gai Mahou de Nidome no Jinsei wo Musou suru~

Once, there was a great sage who sought power and became the strongest in the world.

To settle the score, the sage also used reincarnation magic to follow. However-“As a man, you won’t be able to use magic.”
